30.12 mg
Fom IU to mcg: 50000 IU/1.66 = 30120 mcg
From mcg to mg: 30120 mcg/1000 = 30.12 mg Final Answer
From USDA
To convert Vitamin A as beta-carotene:
From IU to mcg: IU/1.66 = mcg
From mcg to IU: mcg * 1.66 = IU

Ther are 1000 mcg in a mg so to convert to miligrams you have to divide the micograms by 1000.
10000
Beta carotene, or Vitamin A, is fat soluble and has an acute toxicity at 25,000 IU/kg of body weight. 15,000 IU is equivalent to 4500 micrograms, or 45000 milligrams.
1000 RE of Beta Carotene = 6 mg
an IU is not a standardized unit that can be converted to mg with a single formula. IUs means something different for each item (usually vitamins) it is used for. So for one vitamin you could have 1000IUs and it is 10mg, whereas 10mg of another vitamin is only 100IU.
Recalculate it from the IU-definition for VitA, but be sure the difference betweenretinol (C20H30O) and β-carotene (C40H56), both can be taken to be Vitamin A!By definition for Vitamin A:1 IU vitamin A is the biological equivalent of 0.3 μg retinol, or of 0.6 μg β-caroteneExamples:6 μg of dietary β-carotene is equivalent to 3⅓ IU of vitamin A and is equivalent to 3⅓ IU of vitamin A.This same amount also supplies the equivalent of 1 μg of retinol (or 1 RE =Retinol Equivalent) and is also equivalent to 3⅓ IU of vitamin A.So 5000 IU is 1500 μg retinol or 3000 μg β-carotene

Assuming you mean international units for vitamins this question can only be answered for the specific vitamin. Vitamin units are measured by their potency and not by weight.vitamin A for instance:1 IU retinol = 0.3 mcg RAE1 IU beta-carotene from dietary supplements = 0.15 mcg RAE1 IU beta-carotene from food = 0.05 mcg RAE1 IU alpha-carotene or beta-cryptoxanthin = 0.025 mcg RAEas you can see different sources of the same vitamin can have different IU to weight ratios for RAE (retinol activity equivalent)
